Contempt is pretty strong. More indifference from me right now. I share some of the same views made above.
I do feel like vintage has been muddled with the other formats. Many vintage decks are essentially just modern/legacy decks with power. It was not that long ago when vintage decks did not look like decks from any other format.
I don't like a lot of the cards printed recently, especially G.probe, Dig, and Mental Misstep.
Misstep greatly limits my ability to brew which is part of what fuels my fun in an environment.
I don't hate blue, but I do dislike that WOTC gave up on the balancing aspect of blue which was supposed to be poor creatures. Instead, blue has the highest percentage of best creatures among the elite creatures (Delver, Snapcaster, True-name, V.Clique all make my top ten list for best creatures).
Mostly though I am just not that interested in the competitive decks at the moment. I would love for something to shake up the environment in a different way. While PO is fairly new, all it really did was replace storm in the meta so it feels similar. Hollow One just made Dredge competitive again but it's essentially the same deck. I want something that shakes the format up a bit but is not so broken that it's just a short term meta that will be fixed via B&R. I'm not sure what that would take. I think the most obvious way to do this is drastic changes to the current B&R either with a lot of removals or additions, or with some rules changes (like banning instead of restricting) These are very controversial and would bring a bunch of discord. Eventually the meta will shift. It always does and when it does, I'll play more vintage.
